It is pretty obvious. The stomach shrinks over a period of time
when it is not swollen by too much food. It will also increase in size
readily over a shorter period of time if overfilled. Have you ever
noticed that
when you overeat it is not so easy to fasten your belt. But after a
while you have no problem unless you keep eating.

Probably true but very reversible.

Consider what happens when a person has a large part of his stomach
removed during an ulcer operation. (90% actually). It only takes a
few weeks for the remainder of the stomach to stretch to accommodate
the same amount of food as it did before the operation.
